What it is
What is the 4D Barrier Pest Defense System?
The 4D Barrier system creates four treated barriers between the desert and your living space — the fence line, the yard, the home perimeter, and the interior. Our specially trained technicians use the latest IPM devices, products and techniques to establish protective barriers that exterminate and repel pests before they reach your home.
The 4D Barrier Pest Defense System is safe and effective, and specially designed to help you and your family feel secure and comfortable in your home again as soon as possible.
Most pest control treats the house. This treats everything between the pest and the house — which is why the interior needs treating only semi-annually or annually after the initial visit.
How it works
Four barriers, worked from the outside in
- 1
The Fence Line
Pests hit at the property line, before they reach your yard.
- 2
The Yard
Pests hit at pool decks, rock rivers, and grass borders where insects naturally harbor.
- 3
The Home Perimeter
Pests hit at the entire home perimeter. We treat and dust all exterior doors, including garage doors. When possible, we spray around windows, vent frames, and lower eaves.
- 4
The Interior
The last line of defense. Usually only needed once or twice a year.
Four layers. One coordinated defense.

Common questions
Frequently asked questions
The frequency of pest control services depends on the type of pest and the severity of the infestation. Generally, quarterly treatments are recommended for preventive measures, but more frequent treatments may be necessary for severe infestations.
Not usually for an exterior visit. Interior work needs access, so we agree a time window and the technician confirms before arriving. Service is by appointment.
Before our technician arrives, please ensure that all food is stored away, and access points to infested areas are clear. Specific preparation steps will be provided based on the type of pest being treated.
A typical pest control treatment can take anywhere from 30 minutes to a few hours, depending on the size of the property and the severity of the infestation.
Pests can return because pressure changes with weather, moisture and entry conditions. Every service. Guaranteed for 30 days. The guarantee applies to the service provided, while regular maintenance and preventive measures reduce the likelihood of re-infestation.
